"Up for auction is an analog sequencer made by "Davis Development" for use with analog synthesisers that have cv/gate inputs. This unit appears to be either A: a prototype, B: a one-off someone made in the late seventies or C: from a kit. Not sure which, but, have you seen another? I can't find anything online about it, but it seems to have been built by a serious pro. The main board is all point-to-point wiring, but very nicely done (this definitely was not an amateurs work). It has been in fine working condition since I've owned it, although it does show its age here and there (see pics).

It should be noted that this sequencer apparently puts out a "volts per hertz" output at the "pitch out", and a "gate" at the "trig out" (both 1/4"). This explains why it works fine with the EML-101. The EML, Korg MS-series, and a few others use this type of interfacing. ARP, Roland, Moog, etc. use a "volts per octave" system, which seems to be the more common. It works with that type as well, but adds a (sort of) "ring-mod" effect to the oscillator(s) its driving. Just thought you should know, to avoid future issues (don't want any unhappy customers...) :~)

O.K., back to the details. It has a momentary button under each of the 8 steps (handy for "tuning in" your sequence), as well as a "random" on/off button, "clock" on/off, and a "range" thumbwheel switch (for making it 4-step, 2-step, 5-step, etc.). The CV output is not quantized."
